If you have two brain cells to rub together it's not difficult, keeps you out of any possible legal trouble, and you can refer all you want and get a cut of the commission or list yourself. 

Keep in mind that you may have to do some significant rerouting of your plumbing depending on how the builders ran the original pipe, in a top bottom they might have too much common pipe to get the metering done.There are companies out there if you look into it that you can contract with they will install the meters, get the reads over cell signal, and then bill the usage back to the tenants. 

If this is the case the revenue stream most companies will offer 15 to 20 cents on the dollar.I deal with cell tower leases occasionally and they buy futures contracts.The purchaser say on a 30 year payout of 800k will look at risk,inflation,etc.

Are we all paying for our cell phones?

Once the main "cell" is formed and filed with the state, all others should only be internal documentation.

That was in 1971...before computers, before e-mail, before cell phones, etc.Of the 27 amendments to the Constitution, seven (7) took 1 year or less to become the law of the land...all because of public pressure.I'm asking each addressee to forward this email to a minimum of twenty people on their address list; in turn ask each of those to do likewise.In three days, most people in The United States of America will have the message.

For example, driving a car is legal, unless you're doing 80 mph on the sidewalk in a school zone with an expired license while texting on your cell phone without wearing a seat belt.

Today is day 60 on a house that we completely gutted down to the studs that was full of blow in insulation and plaster and lathe It now has all of the plumbing, hvac and electric roughed in, closed cell insulation on the ceilings and walls and will be completely sheet rocked by the end of the week, the upstairs is and half of the living room are ready to be taped as soon as the rest of the house is done.

Or, the building is cancerous.

Alcatel-Lucent makes cell tower equipment.
